CLIMATE CONTROLLED SEAT
PFP:870U6
System Description
AIS002BX
The climate controlled seat system is controlled by climate controlled seat control unit.
Heating and cooling are possible for a thermal electric device (heat conversion machine).
NOTE:
●
The climate controlled seat system is downed when the temperature sensor set as the seat cushion and
the seat back's thermal electric device machine detects 20
°
C (68
°
F) or more of mutual differences of
temperature.
●
In this case, by turning off ignition switch, system down is canceled and it can be reused by turning on
ignition switch again.
●
The climate controlled seat blower keep low speed for approximately 60 seconds after turning the temper-
ature switch or the dial.
CAUTION:
●
The thermal electric device has the character in which, as for an opposite side. one side becomes
high temperature at the time of low temperature.
●
At the time of work, please turn OFF a switch, and carry it out after checking that the thermal elec-
tric device has got cold.
Power is at all times supplied
●
through 15A fuse [No. 71, and 72, located in the fuse fusible link and relay unit]
●
to climate controlled seat relay terminals 5 and 7.
When the ignition switch turned to ON or START position,
Power is supplied
●
through 10A fuse [No. 1, located in the fuse block (J/B)]
●
to climate controlled seat relay terminal 2,and
●
to climate controlled seat control unit (driver side and passenger side) terminal JB.
Then ground is supplied
●
to climate controlled seat relay terminal 1,
●
through body grounds E42, and E 62,
Then climate controlled seat relay is energized,
When climate controlled seat relay is turned to ON,
Power is supplied,
●
through climate controlled seat relay terminal 3,
●
to driver side climate controlled seat control unit terminal JD.
When climate controlled seat relay is turned to ON,
Power is supplied,
●
through climate controlled seat relay terminal 6,
●
to passenger side climate controlled seat control unit terminal JD.
When climate controlled switch select “HEAT”, ground is supply
●
through climate controlled seat switch terminal J6,
●
to climate controlled seat control unit terminal J6,
●
through climate controlled seat switch terminal JCA,
●
through body grounds B17 and B57.
Then, the climate controlled control unit receives climate controlled switch “HEAT” signal.
When climate controlled switch select “COOL”, ground is supply
●
through climate controlled seat switch terminal J16,
●
to climate controlled seat control unit terminal J16,
●
through climate controlled seat switch terminal JCA,
●
through body grounds B17 and B57.
Then, the climate controlled control unit receives climate controlled switch “COOL” signal.
When the climate controlled seat control unit receives climate controlled seat switch signal, power is supply
●
to climate controlled seat temperature dial terminal J7,
SE-98
CLIMATE CONTROLLED SEAT
●
through climate controlled seat control unit terminal J7,
And then ground is supplied
●
through climate controlled seat control unit terminal J15,
●
to climate controlled seat temperature dial terminal J15,
Then, the climate controlled seat control unit receives climate controlled seat temperature dial signal.
When blower motor rotates, signal is transmitted
●
to climate controlled seat control unit terminal J14,
●
through climate controlled seat blower motor terminal J14.
This is climate controlled seat blower motor tachometer signal.
When climate controlled seat control unit receives climate controlled seat switch (HEAT, COOL) signal, climate
controlled seat temperature dial signal and tachometer signal,
Power is supplied
●
to climate controlled seat blower motor terminal J13,
●
through climate controlled seat control unit terminal J13,
This is blower motor revolution control signal.
When blower motor receivers blower motor revolution control signal,
Power is supplied
●
through climate controlled seat control unit terminal J10,
●
to climate controlled seat blower motor terminal J10.
When number of rotations correspond signal,
Ground is supplied
●
to climate controlled seat blower motor terminal J3,
●
through climate controlled seat control unit terminal J3,
●
through climate controlled seat control unit terminal JC,
●
through body grounds B217 and B256.
Then motor revolution is controlled.
When the ignition switch turned to ON or START position,
Power is supplied
●
to climate controlled seat cushion thermal electric device terminal J18,
●
through climate controlled seat control unit terminal J18.
Then ground is supplied
●
to climate controlled seat control unit terminal J17,
●
through climate controlled seat cushion thermal electric device terminal J17,
Then the climate controlled seat control unit recognizes seat cushion thermal electric device sensor signal.
When climate controlled control unit recognizes climate controlled switch “HEAT” signal and, seat cushion
thermal electric device sensor signal,
Power is supplied
●
to climate controlled seat cushion thermal electric device terminal J1,
●
through climate controlled seat control unit terminal J1,
Then ground is supplied
●
through climate controlled seat cushion thermal electric device terminal J2,
●
to climate controlled seat control unit terminal J2.
●
through climate controlled seat control unit terminal JC,
●
through body grounds B217 and B256.
When climate controlled control unit recognizes climate controlled switch “COOL” signal and, climate con-
trolled seat cushion thermal electric device sensor signal,
Power is supplied
●
to climate controlled seat cushion thermal electric device terminal J2,
●
through climate controlled seat control unit terminal J2,
Then ground is supplied
●
through climate controlled seat cushion thermal electric device terminal J1,
●
to climate controlled seat control unit terminal J1.
